Natural cleansers cost a lot and I have found them to not work that great. I found this recipe from Stephanie and thought that I would give it a try. I found that it works at least as well as the regular cleansers you can buy at the store, and better than the natural ones.
Will not deteriorate grout.
2 parts baking soda
1 part borax
few drops essential oil, your choice
The baking soda will absorb the fragrance over time, so it is better to make smaller batches. I put mine in a cheese shaker that has a plastic lid I bought at the grocery store.
